The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

The device has two sides, and when a DC electric current flows through the device, it brings heat from one side to the other, so that one side gets cooler while the other gets hotter. The "hot" side is attached to a heat sink so that it remains at ambient temperature, while the co…

WebFeb 20, 2024 · An artifact of the second law of thermodynamics is the ability to heat an interior space using a heat pump. Heat pumps compress cold ambient air and, in so doing, heat it to room temperature without violation of conservation principles. To calculate the heat pump’s coefficient of performance, use the equation C O P h p = Q h W. WebThe COP characterizes the amount of heat removed from the cooler. The COP for cooling mode is less than for heating mode because the work done by the compressor is …
WebThe calculation method includes finding a COP value for each temperature bin within the temperature interval of the climate zone. This COP gives the electricity consumption needed to meet the heating demand at each temperature. Interpolated values are used for temperatures between the determined test points. WebFeb 7, 2024 · COP is a measurement of how effectively a heat pump uses electricity to move heat from place to place. Specifically, the coefficient of performance of heat pump units is the ratio of the heating and AC output (how much heating and cooling it delivers) to the energy used to power the heat pump.
